Title: Recorder
Inventor: HASHIZUME MASAHIRO
IPC: B65H23/192
Filed: 1990-01-23
Abstract: PURPOSE:To detect a paper jam by providing a setting means of a current value for showing the lower limit of a normal condition of a motor for driving an automatic cutter, current detecting means and judging means for judging an abnormality condition when a current of the drive motor is less than the set current value above-mentioned. CONSTITUTION:When a platen roller 3 is driven to reach the point of time t1 for conveying recording paper 1 to which photographic printing is completed, toward an automatic cutter 4, driving of a drive motor 7 is started by turning a transistor Q1 ON, and cutting is started at the point of time t2 by rotating a rotary edge 5 from a home position. Now in an empty cut condition, a current I5 (two-dot chain line) of the motor is decreased less than the first current value I1 (lower limit value of normal current value or below) at the point of time t3 and a high signal is output to a CPU14 from a comparator 13, and a judging means 15 judges an abnormality condition to turn the transistor Q1 OFF and further to feed a stop signal to a platen roller driving means and an abnormality signal to a display part 16, respectively.

Title: Magnetic recording medium
Inventor: KAWACHI AKIHIKO
IPC: G11B5/72
Filed: 1982-02-01
Abstract: PURPOSE:To provide a recording medium which is hardly flawed and has high reliability by forming a thin film of boron nitride which is oriented perpendicularly to the surface of a thin film magnetic recording medium of cobalt chromium. CONSTITUTION:A ''Permalloy '' film 2 and a cobalt chromium alloy film 3 are the same as the films of the basic structure in the prior art and further, a thin film 9 of boron nitride BN is formed as an abrasion-resistant lubricating layer thereon. According as the thickness of the boron nitride BN9 is increased, reliability is improved, but the output of the reproduced signal decreases. The thickness at which troubles such as increased noises arise is determined by taking the characteristics of the perpendicularly magnetized recording film 2 and heads into consideration. The crystalline structure of the boron nitride BN is the hcp structure which is exactly the same as the structure of the thin film of cobalt chromium; besides, the shortest distances among the atoms of the axis (a) of both are virtually equal. Thus, it is possible to grow the thin film of boron nitride epitaxially on the film of cobalt chromium. In other words, the thin film of boron nitride is oriented perpendicularly to the surface of the thin film of cobalt chromium. Lubricity and abrasion resistance are thus improved.

Title: Pulse arc welding machine
Inventor: MOCHIGURI SHIGEO
IPC: B23K9/09
Filed: 1981-02-03
Abstract: PURPOSE:To make the refiring of the arc easy and to maintain the arc stably in a pulse arc welding machine by setting the output current and voltage characteristics of a base current supplying circuit at constant voltage characteristics. CONSTITUTION:A base circuit 5 is so arranged as to have roughly constant voltage characteristics and therefore when the arc length decreases on account of the operator's hand shaking or the like, current of the base circuit 5 increases by as much as the drop of the arc voltage, thereby increasing the rate of melting of a wire 1. Then, the arc length increases again to the original length and is maintained at a constant length. Further when the wire 1 and base metals 2 short circuit, large short circuiting current flows, and the wire 1 burns out; therefore, the refiring of the arc is easy, and the arc is kept lighted at all times, thus the discontinuity in weld beads is obviated.

IPC: H04N1/409
Filed: 1993-02-02
Abstract: PURPOSE:To automatically constitute an objective picture processing filter. CONSTITUTION:The coefficient of a picture filter is corrected based by learning by using a pixel as a neuron and applying neural network technique to known data to constitute an objective filter. The constitutional condition of a filter required by a designer is set up (S11, S12). Filter constituting data having no directivity to the object are generated based upon known data (S21). The data are convoluted by the weight vector of the filter (S23) and learned based upon Kohonen's learning rule (S24), the size of a window is adjusted by using a Gaussian filter (S25), neuron outputs for all units are calculated, and a winner is determined (S26, S27). The weight vector is corrected based upon a convoluted result (S28) and error evaluation is executed (S29). The above processing is repeated until required accuracy is obtained to correct the weight vector. A filter having the corrected weight vector is practically applied (S31).
